* GH-113171: Fix "private" (really non-global) IP address ranges
The _private_networks variables, used by various is_private
implementations, were missing some ranges and at the same time had
overly strict ranges (where there are more specific ranges considered
globally reachable by the IANA registries).
This patch updates the ranges with what was missing or otherwise
incorrect.
I left 100.64.0.0/10 alone, for now, as it's been made special in [1]
and I'm not sure if we want to undo that as I don't quite understand the
motivation behind it.
The _address_exclude_many() call returns 8 networks for IPv4, 121
networks for IPv6.

Add Py_GetConstant() and Py_GetConstantBorrowed() functions.
In the limited C API version 3.13, getting Py_None, Py_False,
Py_True, Py_Ellipsis and Py_NotImplemented singletons is now
implemented as function calls at the stable ABI level to hide
implementation details. Getting these constants still return borrowed
references.
Add _testlimitedcapi/object.c and test_capi/test_object.py to test
Py_GetConstant() and Py_GetConstantBorrowed() functions.
These give applications the option of more forcefully terminating client
connections for asyncio servers. Useful when terminating a service and
there is limited time to wait for clients to finish up their work.
This is a do-over with a test fix for gh-114432, which was reverted.
* GH-65056: Improve the IP address' is_global/is_private documentation
It wasn't clear what the semantics of is_global/is_private are and, when
one gets to the bottom of it, it's not quite so simple (hence the
exceptions listed).

In Lexical Analysis f-strings section, NULL in the description
of 'literal character' means '\0'. In the format_spec grammar
production, it is wrong with that meaning and redundant if
instead interpreted as <nothing>. Remove it there.
Stop raising `ValueError` from `glob.translate()` when a `**` sub-string
appears in a non-recursive pattern segment. This matches `glob.glob()`
behaviour.

On Windows, time.monotonic() now uses the QueryPerformanceCounter()
clock to have a resolution better than 1 us, instead of the
gGetTickCount64() clock which has a resolution of 15.6 ms.
These give applications the option of more forcefully terminating client
connections for asyncio servers. Useful when terminating a service and
there is limited time to wait for clients to finish up their work.
In free-threaded builds, running with `PYTHON_GIL=0` will now disable the
GIL. Follow-up issues track work to re-enable the GIL when loading an
incompatible extension, and to disable the GIL by default.
In order to support re-enabling the GIL at runtime, all GIL-related data
structures are initialized as usual, and disabling the GIL simply sets a flag
that causes `take_gil()` and `drop_gil()` to return early.
* set default return value of functional types as _mock_return_value
* added test of wrapping child attributes
* added backward compatibility with explicit return
* added docs on the order of precedence

Now the special comparison methods like `__eq__` and `__lt__` return
NotImplemented if one of comparands is date and other is datetime
instead of ignoring the time part and the time zone or forcefully
return "not equal" or raise TypeError.
It makes comparison of date and datetime subclasses more symmetric
and allows to change the default behavior by overriding
the special comparison methods in subclasses.
It is now the same as if date and datetime was independent classes.
By default, it preserves an inconsistent behavior of older Python
versions: packs the count into a 1-tuple if only one or none
options are specified (including 'update'), returns None instead of 0.
Except that setting wantobjects to 0 no longer affects the result.
Add a new parameter return_ints: specifying return_ints=True makes
Text.count() always returning the single count as an integer
instead of a 1-tuple or None.
The `PyDict_SetDefaultRef` function is similar to `PyDict_SetDefault`,
but returns a strong reference through the optional `**result` pointer
instead of a borrowed reference.

* When called with a single argument to get a value, it allow to omit
the minus prefix.
* It can be called with keyword arguments to set attributes.
* w.wm_attributes(return_python_dict=True) returns a dict instead of
a tuple (it will be the default in future).
* Setting wantobjects to 0 no longer affects the result.
Update documentation with `__new__` and `__init__` entries.
Support use of `auto()` in tuple subclasses on member assignment lines. Previously, auto() was only supported on the member definition line either solo or as part of a tuple:
RED = auto()
BLUE = auto(), 'azul'
However, since Python itself supports using tuple subclasses where tuples are expected, e.g.:
from collections import namedtuple
T = namedtuple('T', 'first second third')
def test(one, two, three):
print(one, two, three)
test(*T(4, 5, 6))
# 4 5 6
it made sense to also support tuple subclasses in enum definitions.
The new `PyList_GetItemRef` is similar to `PyList_GetItem`, but returns
a strong reference instead of a borrowed reference. Additionally, if the
passed "list" object is not a list, the function sets a `TypeError`
instead of calling `PyErr_BadInternalCall()`.

Improve misleading TCP server docs and example.
socket.recv(), as documented by the Python reference documentation,
returns at most `bufsize` bytes, and the underlying TCP protocol means
there is no guaranteed correspondence between what is sent by the client
and what is received by the server.
This conflation could mislead readers into thinking that TCP is
datagram-based or has similar semantics, which will likely appear to
work for simple cases, but introduce difficult to reproduce bugs.
The text clearly seems to be referencing `TestFuncAcceptsSequencesMixin`,
for which no target is available. Name the class properly and suppress
the dangling reference.
Return files and directories from `pathlib.Path.glob()` if the pattern ends
with `**`. This is more compatible with `PurePath.full_match()` and with
other glob implementations such as bash and `glob.glob()`. Users can add a
trailing slash to match only directories.
In my previous patch I added a `FutureWarning` with the intention of fixing
this in Python 3.15. Upon further reflection I think this was an
unnecessarily cautious remedy to a clear bug.

nedbat took issue with the phrasing "real module". I'm actually fine
with that phrasing, but I do think the `__future__` page should be clear
about the way in which the `__future__` module is special. (Yes, there
was a footnote linking to the future statements part of the reference,
but there should be upfront discussion).
I'm sympathetic to nedbat's claim that no one really cares about
`__future__._Feature`, so I've moved the interesting table up to the
top.
Add `ntpath.isreserved()`, which identifies reserved pathnames such as "NUL", "AUX" and "CON".
Deprecate `pathlib.PurePath.is_reserved()`.

In 49f90ba we added support for the recursive wildcard `**` in
`pathlib.PurePath.match()`. This should allow arbitrary prefix and suffix
matching, like `p.match('foo/**')` or `p.match('**/foo')`, but there's a
problem: for relative patterns only, `match()` implicitly inserts a `**`
token on the left hand side, causing all patterns to match from the right.
As a result, it's impossible to match relative patterns from the left:
`PurePath('foo/bar').match('bar/**')` is true!
This commit reverts the changes to `match()`, and instead adds a new
`full_match()` method that:
- Allows empty patterns
- Supports the recursive wildcard `**`
- Matches the *entire* path when given a relative pattern
`threading.Lock` is now the underlying class and is constructable rather than the old
factory function. This allows for type annotations to refer to it which had no non-ugly
way to be expressed prior to this.

Allow `os.PathLike` objects to be passed as patterns to `pathlib.Path.glob()` and `rglob()`. (It's already possible to use them in `PurePath.match()`)
While we're in the area:
- Allow empty glob patterns in `PathBase` (but not `Path`)
- Speed up globbing in `PathBase` by generating paths with trailing slashes only as a final step, rather than for every intermediate directory.
- Simplify and speed up handling of rare patterns involving both `**` and `..` segments.
Tkinter is a fact, not necessarily a feature.
Reorganize editor key bindings in a logical order

`PyComplex_RealAsDouble()`/`PyComplex_ImagAsDouble` now try to convert
an object to a `complex` instance using its `__complex__()` method
before falling back to the ``__float__()`` method.
PyComplex_ImagAsDouble() also will not silently return 0.0 for
non-complex types anymore. Instead we try to call PyFloat_AsDouble()
and return 0.0 only if this call is successful.
On Windows, `os.path.isabs()` now returns `False` when given a path that

`ntpath.isabs()`, which corrects its handling of partial UNC/device paths
like `//foo`.

The MagicMock documentation mentions magic methods several times without
actually pointing to the term in the glossary. This can be helpful for
people to fully understand what those magic methods are.
Make zipfile.ZipInfo.compress_level public.
A property is used to retain the behavior of the ._compresslevel.
People constructing zipfile.ZipInfo instances to pass into existing APIs to control per-file compression levels already treat this as public, there was never a reason for it not to be.
I used the more modern name compress_level instead of compresslevel as the keyword argument on other ZipFile APIs is called to be consistent with compress_type and a general long term preference of not runningwordstogether without a separator in names.

When new mailbox.Maildir methods were added for 3.13.0a2, their
documentation was added at the end of the mailbox.Maildir section
instead of grouping them with other methods Maildir adds to Mailbox.
This commit moves the new methods' documentation adjacent to
documentation for existing Maildir-specific methods, so that
the "special remarks" for common methods remains at the end.
POSIX specifies that implementations are not required to support changing the
file mode of symbolic links, but may do so.
Consequently, `lchmod()` is not part of POSIX (but mentioned for implementations
which do support the above).
The current wording of the availability of `os.lchmod()` is rather vague and
improved to clearly tell which POSIX/Unix/BSD-like support the function in
general (those that support changing the file mode of symbolic links).
Further, some examples of major implementations are added.
